(3) Checking the Electrical Parts
1 Power transformer (TR1) ..................... Indoor unit *Measure the coil resistance.
• Primary 230-208V ; Measure the resistance between No.1 and No.3
(WHT lead wires) terminals of 3P (WHT) socket connected to
power transformer.
• Secondary 14.8V ; Measure the resistance between No.1 and No.2
(RED lead wires).
14.8V ; Measure the resistance between No.3 and No.4
(BRN lead wires).
Refer to “1-3 Other component specifications”.
2 Power transformer (TR) ....................Outdoor unit *Measure the coil resistance.
• Primary 230-208V ; Measure the resistance between No.1 and No.3
(WHT lead wires) terminals of 3P(WHT) socket jointed to power
transformer.
• Secondary 14 V ; Measure the resistance between No.1 and No.2
(BRN lead wires).
Refer to “1-3 Other component specifications”.
3 Indoor fan motor (FMI) .........................Indoor unit *Measure the coil resistance.
• Measure the resistance between each terminal of 7P (WHT) socket and 3P (YEL)
socket connected to the indoor fan motor.
Refer to “1–2–(A) Major component specifications”.
4 Outdoor fan motor (FMO) .....................Outdoor unit *Measure the coil resistance.
• Measure the resistance in the same manner as explained above 3.
Refer to “1–2–(B)Major component specifications”.
